Trick for getting the new angle right.
Put the sidestand down and prop it to the level you want. You will have to put stuff under the wheels to get it so the stand can come down below the effective ground level.
When you have that angle, use something parallel to the ground ( block of wood , brick, square etc) and mark the stand shaft ALL the way around to give you a cut guide. Don't forget the thickness of the new bottom plate.
That should give you optimium angle for the cut.
Done it heaps of times.
3 or 4mm thick stainless strap about 32mm wide is best if you can weld it, otherwise same thickness mild steel. Make sure you check where it sticks out when folded up. It can be a bit of a calf sticking item if you don't.

Cut and weld a new broader plate on the bottom. Will be the right height AND less likely to sink in soft stuff. 2 birds...

Re: the clip link. You have it the right way around AND wired. Why change it. ? In over 40 years of riding I have never had clip link, porperly done, fail. Road or track or dirt. And they are easier to clean the chain.
I bought my CB500X as a project as well. My direction was to lighten an unnecessarily overweight little bike with a huge fun factor. Worked so far. Like you my partner has given up riding so I don't get to ride as much as I want.

I can't remember if I posted , but I bought a chinese replacement seat cover for the CBR500R and with very little careful cutting it pretty well fitted straight on. I didn't care about the colour as I intend to use the cover base to attach a rack that I can use the stock key to remove, but there are quite a few available in the Honda colours.
If I was going to use the top I would make a carbon skirt to fill the seat/cover gap.

One thing that can help mitigate the bigger diameter wheel is to drag the rake a bit steeper. I don't know if they have done it on the 2019.
Either way a 19 can be a handful on the road even with excellent tyres. BUT only at the extremes of riding really. My Tr650 Husky had a 19 front and Michelin pilot road 4's Wonderful bike to tour on. Handling was superbly suited to all day cruising and the bigger front gives you good stability on garbage tar  inland roads ( Australia). But if you went unloaded and tried to chuck it around like a boy racer , it would reward you by running wide, no matter how you dragged it into the corner. That was with shortened suspension (50mm less travel to 150mm) and steepened front end. It wasn't a light wheel though , which didn't help ( Chinese mag from BMW's supplier).
A 17 is going to be better for the road. 18 at a pinch.
There are 2 other CB500 models you know if you are road only, and better suited to road work. I have the X because it makes the best tourer of the 3 ( and because it was cheap), virute of the tank size and riding position (with a little modification). The rear subfarme also is strong enough for just about any for boxes etc ...and possibly carrying battle tanks on the back. Read OVER-engineered to Hades...
It is a pity that Honda didn't make a decent all road tourer with this superb motor, but it would cost a fair bit more. Needs 40kg less weight and substantially better suspension and chassis  for that. Honda pretty much have gone super conservative over the last couple of decades. Heavy and reliable, but nowhere near the cutting edge any more.

Thanks for that report on the change of wheel sizes.
I suspected as much from the start. Huge trail can only do so much when you have 17' with relatively low angular momentum. 17 was DESIGNED to turn in , not help you stay upright with big gyro forces.
 At the same speed the momentary velocity of the wheen is the same for both sizes, but the momentun is 1/2 the square of the 2 radii. A 19 of the same mass is approx 25% more stable( more gyro effect) than a 17.  Add a heavier tyre as well and you get a much more stable tyre off road. Then you have the fact that a 19 has a longer contact patch to add.
Then you have the depression displacement difference ( a 19 is displaced less in a hole than a 17 so long as the hole diameter is smaller than the diameter of the tyres)
Not really a surprise what you found.
Of course you can have too much of a good thing. A few years ago they were using 23" wheels and they had to go to such narrow tyres to keep the weight down it was a bit of a failure in most cases. Of course with modern rubbers abd lightweight cord material...

Both will fit. The 60 profile lowers the front and inmproves turn in ( 12mm). The 70 is stock height and in a bit more straight line stable. Take your pick.
60 is a bit lighter as well.

Your right. I missed the "2mm steel" bit. Probably won't crack at that thickness. I just assumed Al for lightness.
 Awesome job for steel. Truly fine workmanship.

Beautifully made work.
Can I suggest so large ( 1.5-2.5mm thick) washers about a radius about 4 times the diameter of the hole, on either side of the case wall, where the bolts go through. If possible with some flexible ureathane or similar glue between to act as a damper.
Aluminium mounted like that is likely to fatigue from the bolt holes outward or radially.

Some boots just won't fit.
Had to buy a new pair of boots at Phillip Island a couple of years ago, when the boots I set out with to get there ( from Bundaberg, 5000km round trip) had the sole fall off on the way.
Found a fantasticly comfortable, great protecting set of adventure boots. Problem was they wouldn't fit between the peg and the gear lever on my TR650 Husky because of  the thickness from the bottom of the sole to the top of the foot!!!!!!. Had to take them back and get a less protective pair. Considering the TR650 IS a real adventure bike, god knows what they would fit on. ( trials bike maybe with the gearchange vertical?).
When adjusting gear levers you need to keep in mind that all the included angles on the shafts and levers should be as close to right angles as possible or you can get actuation problems.
